Abstract: The disclosure provides a heat transfer system having a tubing coil for heating fluid flowing therein, where the tubing coil can be pigged (descaled) while operationally online, instead of offline. The online system uses an assembly of valves and associated equipment to connect to a pig launcher and pig receiver while the system is online. A valve opens and the pig launches into the flow stream under pressure through the valve and travels along the tube with the fluid. The system continues to produce heated fluid with the pig in the flow path. A pig receiver receives the pig after the pigging, and then is isolated from the flow path of the heated fluid by another valve. The pig launcher, pig receiver, and pig are removed, and this process is repeated for any other passes in the tubing coil.

Abstract: The present trash receptacle (and method for using the same) reduces the suction/vacuum effect in the bottom portion of the receptacle as trash bags or polyliners are removed therefrom. The receptacle includes a vent enabling fluid communication from a first chamber section (at the bottom of the receptacle) to a second chamber section which rests above the first chamber section.

Abstract: A receptacle includes a body configured to receive a liner and a cinch disposed on the body. The cinch includes a projection disposed outward of the body and configured such that at least a portion of the liner can be disposed between the projection and the body. The cinch further includes a slot having an open end and a closed end, wherein the slot is disposed substantially adjacent the projection and configured such that at least a portion of the liner can be disposed and retained within the slot.
